Abstract: A method and apparatus for removing coatings and oxides from substrates that includes a conveyor for moving a substrate in a first direction, at least one nozzle positioned away from the conveyor in position to direct the stream of fluid toward the conveyor and a high pressure fluid supply in fluid commination with the nozzle wherein the pressurized fluid supply is arranged to supply a pressurized fluid to exit the nozzle and direct the fluid at a high velocity to a surface of the substrate for removing a liquid or solid film from the substrate. The method includes providing a pressurized fluid to a stationary nozzle, directing the pressurized fluid from the nozzle in a high velocity fluid stream toward a moving object having a coating and contacting the fluid stream with the object whereby a force of the fluid removes the coating.

Abstract: Method, system and apparatus are disclosed for in-vessel composting of organic material. A compost handling apparatus moves forwardly through a bed of composting material in an elongate open bay. Specifically, an agitator comprises a feed belt such as a transversely mounted cylindrical drum, which feeds composting material to a conveyor which lifts the material and projects it rearwardly behind the agitator. A regulator, such as an adjustable deflector, controls the discharge of composting material by the conveyor. The deflector is adjusted as the agitator moves forward through the composting material to develop a level bed in the bay behind the agitator. A sensor may be employed to generate a depth signal corresponding to the depth of the composting material for controlling the deflector.

Abstract: A compost handling machine comprising a carriage to support the machine for movement along a composting bay, and a compost agitating and conveying assembly to agitate compost in, and to move the compost along, the bay. The agitating and conveying assembly includes a conveyor subassembly and a drum subassembly. The conveyor subassembly includes a plurality of lifting cleats that, in use, are moved around a closed path to lift compost in the bay and move the compost rearwardly therein. The drum subassembly includes an agitating drum extending between and supported by a pair of support arms, and the drum is rotated to agitate and comminute the compost in the bay.

Abstract: A composting facility comprising an elongated composting bay, a compost handling machine, and a ventilation system. The composting bay holds organic waste material while that material composts; and the compost handling machine is adapted to agitate the compost in, and to move the compost along, the bay. The ventilation system selectively conducts air into the compost, and this system includes a sensor, recessed in the bay, to actuate the ventilation system when the temperature of the compost rises above a preset value. Preferably, the temperature of the compost varies along the length of the bay, and the ventilation system includes a multitude of sensors to actuate the ventilation system to conduct air selectively into different sections of the bay to maintain a desired compost temperature profile.
